Abstract
1. 1. The carotenoids of the prawn, Penaeus japonicus Bate, have been separated by absorption chromatography and further characterized by their absorption spectra and behaviour on the column.In some cases, reactions for specific functional groups were performed. 2. 2. The carapaces of the prawn contain astaxanthin, phoenicoxanthin, dihydroxy-piradixanthin, 3,3'-dihydroxy-ε{lunate}-carotene, and traces of lutein, zeaxanthin, canthaxanthin, echinenone, and β-carotene. 3. 3. The major pigments of the internal organs of the prawn were found to be: astaxanthin, β-carotene, echinenone, canthaxanthin, 3,3'-dihydroxy-ε{lunate}-carotene and the minor pigment in them was dihydroxypiradixanthin. 4. 4. The following metabolic pathway from β-carotene to astaxanthin was proposed:- β-carotene → echinenone → canthaxanthin → phoenicoxanthin → astaxanthin. © 1972.
